Upper panel: time evolution, for all the computed rotating models (as labeled inside the upper panels), of H- and He-burning luminosities. In the lower panel, the mass coordinate of the H-shell, of the inner border of the convective envelope, of the mass extension of the convective core (heavy-shaded) are plotted. In the lower panel of M3 model, the mass coordinate of the inner border of the convective envelope has been artificially lowered by 0.1 M_⊙.
